Three - a 1995-ish Trek 8000, a beach cruiser of unknown make/model, and a Frankenbike created from a Nashbar MTB frame using parts salvaged from a 1992-ish Mongoose IROC that had a cracked headtube (including some superb Maxis rimmed wheels!). All are used on pavement only. I see no reason why I should get rid of any of them.
